Activision has revealed that Call of Duty: Ghosts has sold-in (sold to retail) over one billion dollars of revenue on its first day of release. The publisher has also highlighted the fact that the game has a number one ranking on Microsoft's Xbox Live.

"Ghosts is an amazing game which ushers in the next generation of Call of Duty," commented Eric Hirshberg, CEO of Activision Publishing.

"This is the must have launch title for the next generation of consoles, and we expect Call of Duty: Ghosts to be the most successful launch title for the Xbox One and PS4 by a wide margin. In fact, according to GameStop, Call of Duty: Ghosts is their most pre-reserved next gen title."

They did not reveal unit sales at this time, but we will probably be seeing that in the near future. This would effectively have the game beating GTA V for the top sales spot, but without unit numbers there is no way to determine if they sold more games or just made more revenue due to sales of more expensive collector's editions and such.

Activision Publishing, Inc., a wholly owned subsidiary of Activision Blizzard, Inc. (Nasdaq: ATVI), announced today that the company sold more than $1 billion of Call of Duty: Ghosts into retail stores worldwide as of day one.

"Call of Duty is by far the largest console franchise of this generation," said Bobby Kotick, CEO of Activision Blizzard. "More people have played Call of Duty this year than ever before, logging four billion hours of gameplay. And in the last 12 months, Call of Duty: Black Ops II, including its digital content, generated more revenues than any other console game ever has in a single year. Although it is too early to assess sell-through for Call of Duty: Ghosts, it's launching ata time when the franchise has never been more popular."

Millions of people are already playing Call of Duty: Ghosts online. Since its release yesterday, Call of Duty:Ghosts has moved to the #1 spot as the most played game on Xbox Live, according to Microsoft. Additionally, Activision confirmed that on the Xbox 360 videogames and entertainment system from Microsoft, average player sessions for Ghosts have been longer than either Black Ops II or Call of Duty:Modern Warfare 3, during the same time period.

Call of Duty: Ghosts launched at 15,000 midnight openings around the world. Fans around the world shared their excitement in social media, with Call of Duty-related terms trending an astounding 20 times globally on Twitter in the last 24 hours.

"Ghosts is an amazing game which ushers in the next generation of Call of Duty. The team at Infinity Ward has delivered yet another epic thrill ride in the campaign, and what I think is our best multiplayer game yet," said Eric Hirshberg, CEO of Activision Publishing. "This isthe must have launch title for the next generation of consoles, and we expect Call of Duty: Ghosts to be the most successful launch title for the Xbox One and PS4 by a wide margin. In fact, according to GameStop, Call of Duty: Ghosts is their most pre-reserved next gen title."
